Plain Markdown Read your .md files in place. Pick a folder on your iPhone or in iCloud Drive. The app lists every .md file inside — nothing more, nothing less. Tap a file to read it; the markdown is rendered with quiet, weight-driven typography that gets out of the way. The app uses Apple's standard folder picker, so it works with iCloud Drive, On My iPhone, and any third-party Files app provider (Dropbox, Google Drive, Working Copy, etc.). Pick once, and the app remembers — drill into subfolders, come back, switch folders. No accounts. No sync engine. No editor. Just a reader. · Folder picker with iCloud Drive and Files-app provider support · Drill into subfolders — back-button navigation · Inline images (jpg, png, gif, webp, svg, heic, heif, bmp, avif) · GitHub-flavored markdown: tables, blockquotes, code blocks, task lists, strikethrough · Adjustable text size (5 steps) · Light & dark mode · Mono body font option for code-style reading · Local only — your files never leave your device Privacy This app does not collect data, display ads, or communicate with any server. The folder picker is Apple's. Files are read on-device only. There are no analytics, no third-party SDKs, no telemetry. Less, but better.
